Soil erosion Soil erosion occurs when soil is removed through the action of wind and water at a greater rate than it is formed SOIL The soil covering the surface of the earth has taken millions of years to form and we must learn to respect it. Soil is formed at a rate of only 1 cm every 100 to 400 years and it takes 3 000 to 12 000 years to build enough soil to form productive land. This means that soil is a nonrenewable resource and once destroyed it is gone forever. If we disregard this‚ a

three major causes of soil erosion: overgrazing‚ over cultivation‚ and deforestation. Together‚ these three problems cause more problems by creating unsustainable societies. Luckily‚ overgrazing‚ over cultivation‚ and deforestation can be fixed and the unsustainable society becomes a sustainable one. Overgrazing is when there are more animals in comparison to land‚ meaning that there isn’t as much food for the animals to eat‚ like grass and plants.
